六十年代以来,特别是推广杂交水稻和桂朝2号等高产良种以来,我省各地出现了不少高产典型田块,充分显示了我省水稻生产的潜力。但由于对水稻高产规律认识还不太清楚,栽培措施上还存在一定的盲目性,高产田块的重演性较差。为了有助于指导水稻大面积生产,必须进一步探索水稻高产规律,因地制宜地制定规范化的栽培措施,确保水稻稳产高产。因此,我们面向黔中地区,于1979～1982年在贵阳开展了常规水稻亩产超1100斤、杂交水稻亩产超1200斤的栽培技术及其形态生理研究,并基本实现了计划指标。
Since the 1960s, especially since the popularization of hybrid rice and high-yielding cultivars such as Gui and Chao-2, many high-yielding typical plots have emerged across the province, which fully shows the potential of rice production in our province. However, due to the unclear understanding of the law of high yield of rice, there is still some blindness in the cultivation measures, and the high-yielding plots have poor repeatability. In order to help guide the large-scale production of rice, it is necessary to further explore the law of high yield of rice and formulate standardized cultivation measures according to local conditions so as to ensure stable and high-yield rice. Therefore, we conducted a study on the cultivation techniques and their morphological and physiological characteristics of rice in Guizhou province from 1979 to 1982 in Guiyang, in which the conventional rice yield exceeded 1100 kg per mu and that of hybrid rice exceeded 1200 kg per mu and basically achieved the planned targets.
